UK arms sales benefiting most from Middle East wars – Middle East Monitor:
Arms sales to Saudi Arabia have been pinpointed as the main cause of the increase. In 2015, the Kingdom setup an Arab coalition to battle in Yemen. Since then it has faced criticism that it has repeatedly and indiscriminately attacked civilians in violation of international humanitarian laws.
In July, campaigners brought a case to the British High Courts in the hope of forcing the UK government to stop selling arms to Saudi Arabia, weapons they say were being used in its war on Yemen. However the court ruled that the UK can continue to sell arms to Saudi Arabia.
